Circulation-Drinking-System for cage rearing, fattening and layers

The LUBING Circulation-Drinking-System consists of the following elements:
1. Water supply
2. Circulation unit
3. Drinking Lines
4. Breather
5. Suspension

1. Water supply

The Main water supply secures anoptimum water quality for a long
service life of the nipple drinkers.
The water should have the quality of drinking water. At any case the water must be filtered.

2. Circulation unit

The circulation unit for recirculation of water in the drinking line. See on the right, “Function”.

3. Drinking lines

The drinking line comprises a feed pipe without nipple and the drinking pipe with nipples. They are coupled into double strands of the required length during assembly.

4. Breather

At the end of each drinking line, the end piece for circulation is installed.
Depending on the cage facility, a breather element or breather tube is attached there. A drain tube can be connected as well, through which the flushing waster can run off during flushing, no matter if you are starting flushing manually or with the automatic flushing system.

5. Suspension

If a suspension is required (e.g. in rearing cages), the drinking line is
connected to the suspension system with stable clips. This permits best flexibility for attachment on site.

Main water supply

Optimum water quality increases the service life of the Drinking-Systems.
With integrated doser for the supplement of vitamins or medicines.

Pressure regulator Optima E-Flush

With the Pressure regulator the water column can be adjusted as needed.
The optional screw-in actuator allows automatic flushing of the drinker line.


In the Mixer additives, e.g. vitamins or medicines, are permanently circulated while being added to the drinking water.

Coupling and suspension

The individual elements are coupled to the desired length.

The suspension is tool-lessly pushed directly onto the profile.

NEW! Front valve

The new front valve facilitates flushing and medication or vaccination processes considerably because the system is no longer controlled at the end of the line but right at the supply.

Drinking nipple

The nipple, which is screwed in directly, can be particularly easily cleaned from the outside.

The versions with the Drip cup can be delivered with two-armed cups, but also with a single-armed one.

The plastic profiles

The 22 mm square tubes can be placed on top of each other or next to each other, adjusted to the present space.


The end piece for circulation with breather works fully automatically, e.g., in connection with the LUBING flushing computer.

It no longer needs to be operated manually even when flushing.


In the Circulation-Drinking-System, the water is continually circulated in the drinking lines. For this, a pump is installed in the function unit that returns the water at a defined pressure into the feed line without drinking nipple. The water runs to the end of the line and flows back to the pump in the nipple line. A float switch automatically monitors operation of the pump. It ensures that it cannot run dry. The desired water pressure in the system is set as usual on the Pressure regulator and read at the breather unit on the Pressure regulator. The adjustment wheel on the circulation unit sets the flow rate of the pump. This setting depends on the installed drinking line length and is performed once with the start-up. The balls in the two front breather units indicate the pressure difference between the upper and lower lines. The principle is designed for the pressure at the end of the drinking line being a little lower than at the circulation unit. Therefore, drinking line lengths of up to 120 m can be implemented with a single front or middle feed point.

The advantages at a glance:

• No standing water in the drinking line.

• Even water temperature throughout the drinking line.

• Even distribution of vitamins and medication.

• Safe water transport through double pipe cross-section and additional pump.

• Drinking lines up to 120 m long, with front or middle feed point.
